∗ About programmable controllers and interfaces If controlling the inverter using an open collector output
programmable controller, the following error signals are sent to the inverter. This is a result of differences in the
height of control power supply potential when the inverter remains ON and the programmable controller is turned
OFF. Always set the inverter lock to prevent the programmable controller from being turned OFF while the
inverter is ON.

Operates by short circuiting between the
input terminal and CC (common). Use for
forward rotation, reverse rotation, and
multi-stage speed.
Control by connecting the input terminal and CC
(common) to the output (non-contact switch) of the
programmable controller. Use for forward rotation,
reverse rotation, and multi-stage speed. Use a 5 mA
transistor that operates at 24 V dc.
